Musicians put together alternative cabinet in conjunction with artist (9)
I believe the answer is:
orchestra
'musicians' is the definition.
(I've seen this before)
'alternative cabinet in conjunction with artist' is the wordplay.
'alternative' becomes 'or'.
'cabinet in conjunction' becomes 'chest' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'with' is a charade indicator (letters next to each other).
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'or'+'chest'+'ra'='ORCHESTRA'
'put together' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for orchestra that I've seen before include "Sort of stall" , "eg Halle" , "Brass, woodwind, strings and percussion" , "alternative to the organ" , "many players" .)
